Electronic ear circuit for the analysis of acoustic properties of food products, with the module of the peripheral hearing system operation hybrid simulation

摘要

the electronic ear is characterized by the fact that has four mutually integrated with each other, which represents the flight modules processes in human auditory processing: module registration signals (a), (b) tercjowego analyser module, data analysis module and the module (c) present and archiving of results (d).working in hybrid mode module (a) has two sensors, the first of which is the elektretowy (3) placed at the inlet of the channel aircraft ear, whereas the second sensor is akcelerometr (4) dociskany to mastoid ear person - tester, both czujn iki are connected by flexible screened cable (5) to form the sensor groupedwhich further is connected with the audio interface (6), which the component computer (7) or any type of external device connected to a computer.
